He aha ka mea PFA? Nānā kikoʻī a me nā hiʻohiʻona noi
I ka ʻoihana kemika a me nā noi ʻoihana koi nui, he mea koʻikoʻi ke koho ʻana i ka mea kūpono - he aha ka PFA? Piʻi pinepine kēia nīnau i loko o ka manaʻo o nā poʻe ʻoihana e pono ai nā mea kūʻē i nā mahana kiʻekiʻe a me ka corrosion. Ma kēia ʻatikala, e hāʻawi mākou i kahi kikoʻī kikoʻī o ke ʻano a me nā waiwai o nā mea PFA a me kā lākou ākea ākea o nā hiʻohiʻona noi.
He aha ka PFA?
PFA (Perfluoroalkoxy) mea he fluoropolymer e pili ana i ka polytetrafluoroethylene (PTFE) ohana.PFA mea hoʻonui i ka mea o processability ma ka hoʻokomo alkoxy substituents, a ua oi aku ka thermoformability a me ka ikaika mechanical kiʻekiʻe e like me PTFE.The kemika waiwai o PFA mea like me ka PTFE, akā, ma muli o kona maikaʻi o ka PFE kaʻina hana, akā, ma muli o kona maikaʻi. a me ka ʻike maopopo, loaʻa ka PFA i nā noi he nui kahi e koi ʻia ai ka hoʻopili pololei ʻana.
ʻO nā waiwai nui o nā mea PFA
Hoʻohana nui ʻia nā mea PFA no ko lākou kūpaʻa kemika maikaʻi loa a me ke kūpaʻa wela. Aia ma lalo iho kekahi o nā waiwai nui o nā mea PFA:
Kū'ē Kūlana Kiʻekiʻe: Hiki i nā mea PFA ke mālama i ko lākou mau waiwai kino a me nā mea kemika ma nā wela wela, a hiki i kahi mahana lawelawe kiʻekiʻe o 260 ° C. Hana kēia i ka PFA i koho maikaʻi loa no nā noi e koi ana i ke kūpaʻa wela kiʻekiʻe.

Palekana Kemika: Hōʻike ka PFA i ke kūpaʻa maikaʻi loa i nā mea kemika a pau, me nā waikawa ikaika, nā kumu a me nā mea hoʻoheheʻe organik. He mea kaulana loa ia i ka ʻoihana kemika, ʻoi aku hoʻi i nā pipeline a me nā moku e lawe ana i nā wai corrosive a me nā kinoea.

ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa a me nā waiwai lāʻau ʻole: ʻO ka coefficient haʻahaʻa o PFA o ka friction a me nā waiwai non-stick i kūpono i nā noi kahi e pono ai e hōʻemi i ka ʻaʻahu a pale i ka hoʻopili ʻana, e like me ka uhi a me nā sila.

ʻO ka insulation uila: Loaʻa i ka PFA nā waiwai insulation uila maikaʻi loa, he mea nui ia no nā noi i nā ʻoihana uila a me nā ʻoihana uila.

Nā wahi o ka noi no PFA
Ma muli o kāna mau waiwai kūʻokoʻa, hoʻohana nui ʻia nā mea PFA i kekahi mau ʻoihana. Eia kekahi mau wahi nui o ka noi.
Nā lako kemika a me ka petrochemical: Ma muli o kona kūpaʻa kemika maikaʻi loa, hoʻohana mau ʻia ʻo PFA e hana i nā linings no nā paipu, nā pahu, nā pamu a me nā moku. Pono kēia mau mea hana i ke kūpaʻa kiʻekiʻe kiʻekiʻe i ka wā e lawelawe ai i nā wai corrosive a me nā kinoea, a hiki i nā mea PFA ke hoʻolōʻihi i ke ola lawelawe o nā mea hana.

Hana Hana Semiconductor: ʻO ka maʻemaʻe kiʻekiʻe o ka PFA a me ka pale ʻana i ka corrosion e lilo ia i mea koʻikoʻi i nā lako hana semiconductor, e like me nā paipu a me nā moku i hoʻohana ʻia i ka hana ʻana i nā ʻōnaehana chemical vapor deposition (CVD).

Nā Lapaʻau Lapaʻau: Ma ka lāʻau lapaʻau, hoʻohana pinepine ʻia ka PFA i ka hana ʻana i nā mea me nā koi biocompatibility kiʻekiʻe, e like me nā catheters a me nā hale sensor.

Ka hopena
ʻO ka loiloi ma luna aʻe e hāʻawi iā mākou i kahi kiʻi akaka o ka PFA. ʻO ka PFA he mea fluoropolymer e pono ai i ka nui o nā ʻoihana. ʻO kona kiʻekiʻe kiʻekiʻe wela ke kū'ē, kū'ē kemika, haʻahaʻa haʻahaʻa, a me nā waiwai insulation uila e hoʻohana pono ia i kahi ākea o nā noi i ka kemika, uila, a me nā kahua lapaʻau. Inā ʻoe e ʻimi nei i kahi mea hiki ke ʻoi aku ka maikaʻi ma nā kūlana koʻikoʻi, ʻoiaʻiʻo ʻo PFA kahi koho kūpono e noʻonoʻo ai.
